Census and Statistics
One of the main ways to locate statistical information is through American FactFinder 2, the Census Bureau’s website for data retrieval. The Census Bureau collects information in a variety of surveys and then provides this information to the survey sponsor. The Bureau of Justice Statistics, The Bureau of Labor Statistics, the Bureau of Transportation Statistics, the Department of Housing and Urban Development, the National Center for Education Statistics, the National Center for Health Statistics, the National Science Foundation, and the Social Security Administration are among the sponsors for which the Census Bureau collects data. These statistics may be found on each sponsor’s agency website or through American FactFinder 2.
FedStats is a government website designed to retrieve statistics from federal agencies and is explained in more detail below.
From the Census Bureau site you can retrieve quick facts, updates about census releases, and explanations about the data the Census Bureau collects.

In order to make Bay Area statistics more accessible, librarians at the MTC (Metropolitan Transportation Commission) library and ABAG (Association of Bay Area Governments)
created this website specifically for Bay Area data from 1860 to the present. Similar to the State and County Quick Facts, this site provides data summaries for population, households, racial/ethnic makeup, income and poverty, employment, and transportation for cities, counties, and census tracts and blocks within the San Francisco Bay Area.
Historic census data from 1790 to the present is also available on this website.
This is the Census Bureau’s website for retrieving census data. Data from the 1990, 2000, and 2010 census can be accessed as well as data from the American Community Surveys, which took the place of the long census form and contain detailed information about communities. The 1-year survey provides annual estimates for geographic areas with populations of 65,000 or more, the 3-year survey provides estimates for geographic areas with populations of 20,000 and more, while the 5-year survey covers geographic areas with populations less than 20,000. It’s important to remember that these surveys provide estimates only. The tables will give margins of error, which you should factor into your results.

The Statistical Abstract of the United States contains social, political, and economic statistics for the United States. Most of the data in the Statistical Abstract is national, but there are some tables, such as population, representing data from metropolitan areas.
Until 2012, The Statistical Abstract was produced by the U.S. Census Bureau’s Statistical Compendium Program and was distributed to depository libraries and available in online format free-of-charge. Due to budget cuts, the Statistical Compendium Program was abolished in 2012. However, Bernan Press will begin publishing The Statistical Abstract in print format in 2012 and an online version will be available for purchase. Oakland Public Library will purchase print copies from Bernan Press beginning in 2013, but we will not have online access to current issues. Online data from 1878-2012 will be available on the Census Bureau’s website at the URL listed above.
